<h3>
Answer: B. x = 6</h3>
==========================================================
Explanation:
Since the vertical lines are parallel, this means the alternate exterior angles shown are congruent.
Set them equal to each other and solve for x.
15(x+2) = 120
15x+30 = 120
15x = 120-30
15x = 90
x = 90/15
x = 6
Or we could have the steps like this
15(x+2) = 120
x+2 = 120/15
x+2 = 8
x = 8-2
x = 6
Okay so you can add up all the marbles to find a rate and divide.
Total: 20 marbles
Blue: 25% chance
Red: 40% chance
Green: 45% chance
Answer: 2/25
Step-by-step explanation:
The formula to find the slope is (y2-y1)/(x2-x1)
If you plug in the numbers, you get (18-14)/(30-(-20))
Solve the expression and you get 4/50 = 2/25
So your answer is 2/25
